Android Listview 项目在 10 秒后自动更改？

Question

我有两个数组列表，一个是出发列表，一个是到达列表我想显示这个列表

或者表示 10 秒后列表自动更改

前 10 秒出发列表和后 10 秒到达列表我会把我的代码放在这里我会尝试使用 usint runnable 但我的应用程序在运行此代码时挂起

Home activity.java

  final int []sliderImageArray={R.drawable.banner,R.drawable.banner01,R.drawable.banner02};
        final int []footerImageArray={R.drawable.bottomadv,R.drawable.sandwich,R.drawable.underbig};
        try 
        {

            Log.e("Land Scape Run","");
            Log.e("LandScape  Run","Handler ");
                final Handler imagehandler = new Handler();

                Runnable runnable;

                runnable = new Runnable()
                {

                    int i=0;
                    public void run()
                    {   // slider image run
                        imageslider.setImageResource(sliderImageArray[i]);  //Log.e("Image Run",""+sliderImageArray[i]);
                        i++;
                        if(i>sliderImageArray.length-1)
                        {

                        imagehandler.postDelayed(this, 4000); // for interval
                    }

                };

Answer 1

Handler handler = new Handler();

handler.postDelayed(new Runnable() {
@Override
public void run() {

//do anything


}
}, 10000);

这段代码几乎是一样的。您可以尝试创建延迟 10 秒的两种方法的“递归调用”
